Pulse Technologies -Model HSR -Hierarchical Surface Restructuring Technology

Electrodes and microelectrode arrays in most long-term implantable neurostimulation devices demand low impedance for sensing and recording applications, and high charge injection capacity to achieve safe and reversible stimulation. Electrodes with larger geometric surface area perform better, but they take up more space, limit the device’s spatial selectivity and can harm patients. Maximizing device performance and selectivity often requires introduction a larger number of electrodes or constructing a microelectrode array to activate more neurons or discrete groups of neurons.
